A company faces a hefty fine after four men were found illegally working on its premises. If the employer, Sher Foods, is unable to provide evidence that legally-required checks were carried out before giving the jobs to illegal workers, up to £10,000 will be imposed for each offender. David Griffiths, head of the UK Border Agency's north Wales local immigration team, said more operations to tackle immigration offenders were planned. "Illegal working has a serious impact on communities, taking jobs from those who are genuinely allowed to work," he said.
